Two of my images were incorporated into a video on the Sigma DP Merrills (more than one video actually). YouTube did respond.
Probably there are thousands of my images out there being used without permission, but I’m just not going to worry about that battle.

I too am concerned about images on my website being stolen. Here's a quick, easy and free way to check the entire Internet to see if someone is using one of your images.
1. Open the Google "Chrome" browser on your computer.
2. Right click on the image you want to check.
3. Select "Search Google For This Image" in the drop down box.
That's it! I've caught many people who've stolen my images. If they have a legitimate website they will usually take down my image after I contact them.
DIGLLOYD: good tip, though it won't find images turned into video as was the case above, or at least I think it won’t.
